Enclaving refers to designating islands of extreme or high security within a sea of moderate security.

• A. Islands...Sea
• B. Rooms inside a facility
• C. Zones within a fence
• D. Levels of access within a building

Answer: (A)

Enclaving is about creating isolated pockets of high security inside a broader environment that is comparatively less secure. These high-security pockets, or “islands,” are physically separated from surrounding areas and often have their own independent access controls, monitoring, and barriers. The idea is to protect critical assets by making them stand out as distinct, secure zones within a sea of moderate security.

This concept is best conveyed by describing high-security islands within a sea of moderate security, which captures the contrast between the protected area and its surroundings. Other options describe securing individual rooms, zones inside a fence, or varying access levels within a building, but they don’t convey the notion of discrete, standalone high-security pockets embedded in a less secure environment.
